1、 Spunlaced non-woven fabric

Spunlacing technology is to spray high pressure micro water onto one or more layers of fiber mesh, so that the fibers are intertwined with each other, so that the fiber mesh can be reinforced and has a certain strength.

2、 Heat sealing non-woven fabric

Thermal bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber mesh, and then heating, melting, cooling and strengthening the fiber mesh into a cloth. 

3、 Pulp air laid non-woven fabric

Air laid non-woven fabrics can also be called dust-free paper and dry papermaking non-woven fabrics. It uses the air flow forming technology to open the wood pulp fiberboard into a single fiber state, and then uses the air flow method to make the fiber agglomerate on the net curtain, and then the fiber net is reinforced into cloth. 

4、 Wet process non-woven fabric

Wet non-woven fabric is to loosen the fiber raw materials placed in the water medium into a single fiber, mix different fiber raw materials at the same time, and make fiber suspension slurry. The suspension slurry is transported to the netting mechanism, and the fiber is netted in the wet state and then consolidated into cloth. 

5、 Spunbonded non-woven fabric

Spunbonded non-woven fabric refers to that after the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a mesh, and the mesh is then turned into non-woven fabric through self bonding, thermal bonding, chemical bonding or mechanical reinforcement.

6、 Melt blown non-woven fabric

The process of melt blown non-woven fabric: polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh forming - reinforcement and cloth forming.

7、 Needle punched non-woven fabric

Needle punched non-woven fabric is a kind of dry non-woven fabric. Needle punched non-woven fabric uses the puncture effect of the needle to reinforce the fluffy fiber mesh into a cloth.

8、 Sewing non-woven fabric

Sewing non-woven fabric is a kind of dry non-woven fabric. The sewing method is to use the warp knitting coil structure to reinforce the fiber mesh, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
